Abstract
Diffusion of a thermalized electron in the field of a Coulomb centre is considered. The time dependence of the probability for the electron not to be captured by the Coulomb centre (μ +) at the momentt,P D (t), is obtained. The quantityP D (t) coincides with the precession amplitude at the muon frequency and is determined by the parameterΔ/l CT (Δ is an averaged distance from an electron to a muon att=0 andl CT =e 2/(2T) is the Onsager length) that reflects the relation between electron potential and kinetic energies at t=0. WhenΔ/l CT −1 the precession amplitudeP D (t) decreases up to 30% during the timel 2 CT /D-(D-is the diffusion coefficient) and then it becomes almost constant. The dependence ofP D (∞) onΔ/l CT is presented.
